section taken substantially on a broken line section taken on a broken line 4, 4 of Fig. 1;

Fig. 5 is a fragmentary detail view,

partly in vertical section, showing the disc roller mountings and associated parts;,and

Fig. 6 is a fragmentary view partly in vertical section showing the means for raisingand lowering the body frame.

Referring to the drawings, throughout which like reference numerals designate like parts, the numerals 5 and .6 designate the side walls of the supporting body frame which are held in spaced apart relation at their upper edge portions by transverse L shaped beams 8, 9, 10 and 11. .The forward ends of said side walls are-cut away and their outer end portions are bent inwardly angular spanner member 13.

where they are bolted, as at 12, to an A looped clevis 14 is centrally secured to said spanner member for attaching the propelling means.

Pl ates,15, are bolted to. the forward end portions of said side walls (and curvedout- 17 of ,castors; 1.8 are revolubly seated within sa d, apertures, and serve together as bears ward-1y ,at their; middle portions to formrounded vertical aperturesulti. Standards ings .for' the forward end of the supporting body frame. Plates 19 ar secured to the reduced end portions and are similarly curved to formrounded verticalapertures ,70 20. wherein standards 21 of castors 22 are seated and serve as bearings for the rear end of said supporting bod The means for lowering'and raising the supporting'body frame comprises caps 23 adapted to revolvably seat on top of the standards 17 and 21 having adjustable screws 24 through the lower endportions thereof adapted to fit in annular grooves 25. Sleeves 26 are formed on the upper end portions of said capswhich serve as bearings for transverse Windlass rods 27 havin square ends 28 projecting outside of said sleeves. Cables 29 hav' their-upper ends secured within holes 30 and, their lower ends secured to the transverse beams 8 and 11,

are adapted to be wound around said windlass rods by turning same with detachable handles 31 applied to the square ends 28. Lug brackets 32 are secured to the side walls 5 and 6 and serve as stops for said handles to prevent same from turning backwards. It will now. be apparent that the entire supporting body may be raised or lowered on said standards to suit the nature of the soil and othersurface conditions.

For the purpose of mashing down weeds, stalks and stubble, I have provided a shaft 33 extending transversely adjacent the lower forward end portions of theside walls 5 and 6, with traction rollers 34 and 35 fixedly mounted thereonadjacent the inner sides of said walls. A plurality of rollers 36 are rotatively mounted on said'shaft be-' tween saidv traction rollers with sufiicient corners.

to a short crank shaft 41, more fully hereinafter described, and the arm is pivotally secured at its upper end to a stub shaft 42 mounted in a bearing on the upper flanged portion of the side wall 6. baid arms are of equal length and slots 43 are provided in said side walls concentric with said crank and stub shafts so that when the rollers 36 pass over an obstruction they will be lifted as said arms swing upwardly about their pivotal bearings carrying the shaft 33 within said slots. 7

A shaft 44 is mounted in bearings through the side Walls 5 and 6 adjacent the lower and rear end portions thereof and traction rollers 45 are fixedly'secured thereto adjacent the inner sides of said walls. A plurality of disc rollers 46 are rotatively mounted on said shaft between said traction rollers with sufficient space therebetween to permit independent rotary motion necessary in turning corners. A sprocket wheel 47 is secured to the end of said shaft exteriorly of the wall 5 and a sprocket chain 48 leads upwardly to a corresponding sprocket wheel 49 fixedly secured to the outer end of a roller shaft 50 mounted in bearings on the upper flanged portion of said side walls. A hopper 51 is superimposed on the body frame and is. detachably secured thereon by an angle bracket 52. Referring to Figs. 2 and 3 it will be seen that fertilizer, grain or other material may be automatically fed from said hopper by the rotary motion communicated to said roller when the device is drawn over the ground.

A sprocket wheel 53 is secured to the outer end of the shaft 33, exterior to the wall 5, from which a sprocket chain 54 leads upwardly to a similar sprocket wheel 55 secured to the crank shaft 41. Said crank shaft is mounted in bearings on the upper side of the body supporting frame and is provided with a clutch 56by means of which it may be thrown into or out of action. The crank portion of said shaft is connected to the plunger of a puin 57 and it will be obvious that as the device is drawn over the ground motion will be communicated to said pump whereby air may be forced upwardly through the pipe 58 and into the upper portion of a fuel tank 59 above the liquid fuel contained therein.

The cylindrical tank 59 rests in supports 60 and is secured thereon by straps 61 fastened to the transverse beams 10 and 11. An opening for filling said tank is centrally provided in the upper side thereof and a screw cap 62 is arranged to cover same to prevent the escape of air under pressure. A gage 63 is provided to indicate the pressure within said tank and a safety valve 64 is provided for limitin said pressure.

The pressure within the tank 59 forces the liquid fuel through a centrally located supply pi e 65, having a cut 05 valve 66 therein, an distributes same through a plurality of T connections 67, having regulator valves 68 thereon, to a double set of de riding branch feeder pipes 69 and 70. Sai T connections are supported by a central longitudinal plate 71 horizontally secured to the beams 9 and 10, and a vertical partition 72 projecting downwardly from said plate and secured at its upper edge portion to the underside thereof by angle brackets 73 and 74, divides the 'body portion of the vehicle into two compartments 75 and 76.

The feeder pipes 69 and 70, projecting downwardly adjacent the partition 72 into the compartments 75 and 76 respectively, are bent to form horizontal portions 77 and 78 extending across the lower portions of said compartments close to the side walls 5 and 6 where they are again bent spirally back upon themselvesto form a lurality of gas generator coils 79 and 80 w ich end in closure caps 81 and 82. Said coils are respectively supported by brackets 83 secured to said side walls and central partition and the liquid fuel is thoroughly gasified b this arrangement before it reaches the disc ar perforations in the lower portions of said coils where it is ignited as is well understood.

The compartments 75 and 76 are rovided at their forward ends with an a justable wind shield 84 hingcdly secured to the beam 10 and at their rear ends with a corresponding wind shield 86 secured to the beam 9. Each of the generator coils 79 and 80 is rovided with fenders 88 secured at their en to the side walls 5 and 6 and partition 72 and arranged transversely of said compartments slightly forward of said coils to rotect same from damage by any passin 0 ruetion and also to strengthen the b0 y frame.

In order to provide adequate draft for the burner elements, hoods are superimposed on the body frame over the compartments 75 and 76 comprising 'complemental halves 89 and 90 which are provided at their lower portions with horizontal flanges 91 and 92 adapted to seat on said body frame, and at their upper portions with vertical flanges 93 and 94 which are secured in spaced apart relation by spreader bolts 95, thus forming vents 96 and 97 through which the fumes are permitted to escape.

It will be evident that other com artments may be laterally added to the evice by simple alterations, and that same may be reduced to a single compartment if so desired. A seat, not shown, is ordinaril provided for the operator, and the device is drawn over the ground b animal or automotive wer either by itse f or in tandem with a pldiigh, harrow or other agricultural implements. Therollers 36 mash the weeds down so that the flames from the oil burner will strike their roots. It will be understood that the fuel ressure is regulated to project flames suflicient to destroy all insects and germinant properties of deleterious vegetation and also .that the device is drawn over the ground at a speed regulated to prevent said flames from having any harmful elfects on the life of the soil. The discs 46 serve to extin h the fire and also to chop up the sta s of charred weeds and other growth which is afterwards plou hed under thus adding to the fertility of t e soil.

From the foregoing description taken in connection with the accompanying drawings, the form of construction and method of operation of my weed burner will be' bllI'IllIlg means supported at the lower portion of said walls, and a plurality of rotatively mounted on a shaft within end walls for extinguishing the flames when said weed burner is moved over the ground substantially as specified.

2. The herein-described weed burner comprising a body havin side walls arranged to serve as a dra chamber, weed burning means supported at the lower portion of said walls, a plurality of roller members mounted on a shaft within said walls for mashing the weeds and pivotal means whereby said rollers and shaft may swingingly pass over an obstruction substantially as specified.

3.
